SASH-WEIGHT.

SPECIFICATION forming part of Letters Patent No. 244,123, dated July 12, 1881.

Application filed January 81, 1881. (No model.)

i struction of the weight, as more fully hereinafter described.

In the accompanying drawing, which forms a part of this specilication, my invention is shown in vertical section and represents a hollow cylinder, A, which, however, may be of any suitable or desired form, provided with a top, B, cast integral therewith, and through which there is cored or drilled a hole, a. The bottom C is also solid, except an orifice or hole, b, by means of which communication is had with the interior. These shells are cast upon a core, which is subsequently removed through the aperture b in the bottom.

In practice, the weight of the article which these weights are designed to counterbalance being known, sand or other suitable material maybe filled in through the aperture in the bottom until the counter-balance is of the requisite weight, when the aperture may be closed by a wooden or metal plug.

By this construction the user at a distance from the foundry can nicely adapt his weight to the purposes designed, while the founder is enabled to furnish the shell at a less expense than when the weight is wholly of cast metal, and the necessity of having so many patterns of so many sizes of weights is avoided.

I am aware that itis old to cast sash-weights around a central core of sand for the purpose of using less iron; and I am also aware that scale-Weights have been constructed to receive shot for properly adjusting their weight, and therefore I do not claim either of said inventions.

In my invention the core is used only for making a hollow chamber, into which sand or other suitable material is placed, to cause the weight to exactly balance the sash with which it is used. More or less sand can be used for heavier or lighter sashes.

By contracting the lower end of the weight the opening can be closed by a small plug, which is not only easier litted, but will not be so liable to be pushed out by the pressure of the filling material as when a larger plug of the full size of the diameter of the chamber is used.

By contracting the end of the Weight, as above described, to form the small opening b, the end is made round on the outside, and is not so likely to catch against the sides of the sash-box as a Weight having its end made with a square edge.

What I claim as my invention is- As a new article of manufacture, a sashweight having at its upper end an eye or hole, a, for receiving the sash-cord, and cast with a chamber, A, for receiving sand or its equivalents, said chamber being contracted at its bottom to form an opening, b, through which the filling material is passed, and forming a rounded lower end to the Weight to prevent catching in the sash-box, substantially as de-
